Starlite and Cinnabar Specific Gravity
Another important criteria for qualitative analysis of gemstones is Starlite and Cinnabar Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Starlite and Cinnabar Optical Properties during the identification of gemstone. Specific gravity of Starlite is 2 whereas that of Cinnabar is 2.
